Inose, who played a major role in Tokyo's successful bid to host the 2020 Olympics, resigned Thursday after revelations that he received a 50 million yen loan ($480,200) from a scandal-tainted hospital company.

Takeda said "Tokyo 2020's immediate focus remains firmly on finalizing the establishment of the organizing committee to ensure the successful delivery of the games."

While Inose played a positive role in the Olympic bid, he came under fire in April for suggesting rival Istanbul was less developed and less equipped to host the games than the Japanese capital.

Takeda called Inose a "fervent and enthusiastic supporter" of Tokyo's bid.
